Singleton used to signal "Anonymous Sender" The Anonymous object is used to signal that the sender of a message is not specified (as distinct from being "any sender"). Registering callbacks for Anonymous will only receive messages sent without senders. Sending with anonymous will only send messages to those receivers registered for Any or Anonymous. Note: The default sender for connect is Any, while the default sender for send is Anonymous. This has the effect that if you do not specify any senders in either function then all messages are routed as though there was a single sender (Anonymous) being used everywhere.
